一类Kolmogorov系统的浑沌与次谐分枝

Chaotic Behavior and Subharmonic Bifurcations of a Class of Kolmogorov System

研究一类非Hamilton可积的Kdmogorov生态系统的周期激励模型。应用Melnikov方法，得到了该系统产生浑沌与次谐分枝的参数范围。

This paper studies the periodic excitation model of a class of non-Hamiltonian integrable Kolmogorov ecosystem. The region of parameters,in which the system emerges chaotic behavior and subharmonic birfurcation,is obtained by using Melnikov's method.
